temp & reversible reactions

• What principle is discussed in relation to equilibrium in the video?

  Le Chatelier's principle
• What does Le Chatelier's principle state?

  If a system at equilibrium experiences a change, it responds to counteract that change
• What is the reaction mentioned in the video involving NO2 and N2O4?

  NO2 is forming N2O4 in a reversible reaction
• What type of reaction is the forward reaction in the NO2 to N2O4 process?

  The forward reaction is exothermic
• What happens to the temperature of the system during the forward exothermic reaction?

  The temperature of the system increases
• What is true about the reverse reaction in a reversible reaction where the forward reaction is exothermic?

  The reverse reaction is endothermic
• What happens to the temperature of the system during the reverse endothermic reaction?

  The temperature of the system decreases
• What happens to the equilibrium if the temperature of the system is increased?

  The equilibrium shifts to the left
• Why does the equilibrium shift to the left when the temperature is increased?

  To reduce the temperature since the reverse reaction is endothermic
• What happens to the amount of NO2 and N2O4 when the temperature is increased?

  The amount of NO2 increases and the amount of N2O4 decreases
• What happens to the equilibrium if the temperature of the system is decreased?

  The equilibrium shifts to the right
• Why does the equilibrium shift to the right when the temperature is decreased?

  To increase the temperature since the forward reaction is exothermic
• What happens to the amount of N2O4 and NO2 when the temperature is decreased?

  The amount of N2O4 increases and the amount of NO2 decreases
• What are the effects of changing temperature on a reversible reaction at equilibrium?

  • Increasing temperature shifts equilibrium to the left
  • Decreasing temperature shifts equilibrium to the right
  • Forward reaction is exothermic, reverse reaction is endothermic
